Didn't expect that I'd ever jump in in defence of SAP. But I cannot agree with linking SAP and its sustainability efforts (regardless of its in/effectiveness) to its customer base. If their customer chose a different system, there'd probably be no change at all in carbon circulation.
If you want to assess SAP's sustainability effort related to their customers, you'd rather find out if SAP products help their customers becoming more sustainable. (I'd be surprised if they did, but that's not the point.)
